AUTOMATIC WASHER COMPANY, OF NEWTON, IOWA, A CORPORATION OF DELA- WARE WBINGER Application filed June 11, 1927. Serial No. 198,105.

This invention relates to wringers.

One of the objects of the invention is in the provision of a stamped steel wringer of such simple construction that same may be manufactured at a minimum cost.

Another object is in the provision of a stamped steel wringer fashioned in a simple and sturdy manner, same being adapted to be taken apart with the minimum of effort, to permit replacement or repair to the rollers or ressure and release mechanism.

till another object is in the provision of a stamped steel wringer mechanism comprising a quick release means fashioned in such manner that the release portion thereof may be operated with much less effort than is ordinarily required.

A further object is in the provision of safety release mechanism for the pressure applying means in the wringer, wherein the release member is much more sensitive than in the conventional wringer.

A still further object is in the provision of quick release mechanism that is associated with the upper frame of the wringer in such manner that same is released in a substantially horizontal, rather than a vertical, man.- ner, thereby permitting a much more sensitive adjustment of the safety mechanism.

An additional object is in the fashioning of a stamped steel wringer, wherein the drain board is formed integrally with the wringer framework, thereby obviating a number of wringer parts, said wringer also comprising a quickly detachable framing portion, which in turn carries the entire pressure applying mechanism and quick release mechanism, which is not only simple in construction, but operated with a minimum of pressure.

Other objects will appear in the following specification, taken in connection with the annexed drawings, in which Fig. 1 is a plan view of my wringer, with the safety mechanism in its released position;

Fig. 2 is a side elevation of the wringer, with portions thereof broken away for a more detailed elevational view of the safety release mechanism;

The present applicant has developed here in a stamped steel wringer, simple in construction, one having all of the advantages of even the most expensive wringers, and associated with such simple structure a safety release mechanism of a much more sensitive nature than is found upon any wringers that are known in the trade today. With all the advantages of the sturdy stamped steel construction, the quick demountability of the wringer, and the quick release mechanism, nevertheless, said wringer may be built at an extremely low cost.

In the drawings, it is found that the wringer is made up of a lower frame portion and an upper frame portion. frame portion'comprises a stamped metal drain board 10, the side portions of which, namely 11 and 12, are formed integrally therewith and provide the necessary guideways or receiving portions for the bearings of the wringer rolls.

To completely house the bearing portions within the guideways 11 and 12, it IS necessary to attach thereto the lower end portions 13 and 14. These portions 13 and 14 may be secured to the bottoms of guideways 11 and 12 in any suitable manner. By stamping the drain board and the guideways 11 and 12 in one piece, the necessity of continuing the framing entirely beneath the drain board is obviated, thereby saving a considerable amount. of material and without lessening the strength of the wrifiger. The manner of mounting the wringer rolls l5 and 16 within the lower frame is conven- The lower tional in all respects, except that in this infra iemternbe p. .2 also sery t page? h 1 y ntense; .7

The flat spring 5-29 is held the tour depending arms 32 of the quick release member 33. This quick release member comprises 'not only the four-depending arms 32, which 7 support the flat' spring and project interiorly of the upper frame 21, but also the-portio'n 34, which is disposed upon the exterior surfaceof the upper. frame 21.

It is apparent that same may be manually manipulated to apply proper tension. .i r V Abutments -14 are. shown on the Hat spring s screw 43 which 29, which said spring prevent normal displacement of from an operative position with respect to the depending arms 32. However, it might be stated that by complete withdrawal of the tension screw 43, the flat spring may be turned to such position as to permit its detachment from the upper framing.

With respect to the disposition of the manual release member 38, adjacent the quick release portion 34. in a manner to control the substantially horizontal movement thereof, it may be stated that such mounting of the quick release handle permits a very sensitive safety mechanism and one upon which only a very slight manual pressure is necessary to release the member 34 and therefore the tension upon the Wringer rolls applied by the at spring.

Quick release mechanisms and safety release mechanisms are undoubtedly very old in the art and ordinarily include an upper framing member, a flat spring, or at least spring tensioning means. a quick release portion, a tensioning screw, and a manually operated release member. However, in all of the wringer mechanisms in which the above structure is shown and which, in terms is similar to applicants, the manual release member is so associated with the quickly detachable member that when released, the release member moves rtically rather than both sidewardly and upwardly, as in the present instance. The effect of the movement in the present application with respect to the vertically movable quick release mechanism is as follows: In ordinary wringer construction, whenever the manual release member, or rather, the operation of the holding mechanism in connection therewith, completes the tension connection between the quick release member and the upper wringer rolls, there is considerably more tension to be overcome by movement of the manually movable member than there is in the present instance, wherein all the manual release member does is to prevent the quick release member from moving substantially horizontally and not vertically. This holding of the quick release member from movement horizontally permits a much more delicate adjustment of the quick release mechanism. and therefore a very slight pressure upon the handle 38 to "elease the spring tension.

Quick release mechanisms are absolutely necessary upon wringers. for the purpose of safety and in a great many instances, these quick release mechanisms have required so much pressure to release the same hat women, who have had their fingers caught between the wringer rolls have been unable to release the same. It is the chief aim of the applicant in the present wringer construction to provide a very sensitive adjustment of the safety mechanism, and one which will permit the application of very slight pressure to overcome the tension which is applied to the wringer rolls.

As far as the operation of the device is concerned, the manner of detaching the upper framing from the lower frame portion is thought to have been clearly described, and as respects the application of tension to the wringer rolls, it is merely necessary to release the manually operated screw 42 in the conventional manner, thereupon move the handle 38 to a position to Wedge the quick release member 34, or rather the angulal portion 36 thereof under the upper side of the frame 21, whereupon the screw 42 may be manually operated to apply the desired tension to the spring 29, which in turn applies pressure to the upper wringer rolls.

The cam 40 of the manual release handle 38 normally abuts the projection 41 upon the quick release portion 34 and holds same wedged in a horizontal manner with respect to the upper frame. To release the tension, all that is necessary is to apply a slight pres sure upon the handle 38, and to force the same to an offset position with respect to the abutment 41, whereupon the quick release mechanism does not move vertically to release tension, but moves both horizontally and upwardly, thereby releasing tension upon the ringer rolls and preventing any possible accidents.

Attention is again called to the integral fashioning of the drain board to form the lower framework of the wringer, side portions of which provide the guideways for the bearing blocks, which are removably mounted therein. As stated before, this fashioning of the lower framework of the wringer in connection with the drain board provides a sturdy and simple construction and one that may be produced at a relatively low cost. Likewise, such fashioning permits the detachable mounting of the upper frame portion which carries the quick release mechanism.
